BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The invention herein relates to finger rings, specifically an adjustable circumference finger ring capable of being pivoted apart and, furthermore, varied in circumference.

[0003] 2) Description of the Related Art

[0004] Finger rings are currently the most commonly observed type of ornamental jewelry and in order to further attract consumers with a newer varieties, many manufacturers are focusing on breakthroughs in exterior appearance and minimizing ring wearing problems. The most typical problem is that finger diameter and the fixed circumference of annular band do not match, resulting in easy loosening or wearing difficulty. The approach usually used by manufacturers to solve this problem is to produce a same model finger ring in a range of different circumferences for wearer selection. As a result, finger ring production cost is higher and does not meet the requirements of economic advantage. Another approach is to design the annular band of the finger ring in a expandable arrangement and thereby utilize the material of the annular band to fabricate a finger ring that accommodates fingers of differing diameters. However, since such annular bands tend to contort, an appealing circular shape cannot be maintained.

SUMMARY OF THE INVENTION

[0005] The primary objective of the invention herein is to provide an adjustable circumference finger ring in which the user can wear and remove the finger ring without sliding it past the finger joint and wherein the circumference of the finger ring is adjustable to accommodate finger diameter to thereby increase wearing comfort and prevent the dislodging of the finger ring.

[0006] Therefore, the technological means to achieve the said objectives of the invention herein includes: the finger ring is comprised of two semicircular members and a flexile linkage structure that couples one extremity of the two semicircular members such that the two semicircular members can be spread apart, with the two semicircular members and having a circumference adjustment structure disposed at their opposite extremities that enables the circumferential variation of the finger ring as required to accommodate the finger diameter of the wearer.
